Patent GB-473202-A (GB)
Title: Improvements in and relating to retractable undercarriages for aircraft
IPC: B64C25/22
Filed: 1936-04-08
Abstract: 473,202. Aircraft landing - gear. DOWTY, G. H. April 8, 1936, Nos. 10380 /36, 33845/36, 236/37, and 952/37. [Class 4] In a fluid-pressure jack-operated retractable undercarriage for aircraft a locking member preferably coacting with elements on the fuselage or undercarriage radius rod or stay is operated in series with the stay, a lost motion device being incorporated so that, in retracting or extending the undercarriage, the operation of the stay is preceded and/or followed by unlocking or locking of the lock in the necessary sequence. In the construction shown in Fig. 2, the wheel-carrying leg 20 is pivoted to the fuselage at 20A and maintained in extended position by a two-part stay 21, 22 controlled by a jack 23, a locking- pawl 27 having two notches 27A, 27B being pivoted on the part 21 and being actuated by a link 28 connected to a lug 24B on the end of the jack piston 24. The lug 24B has a slot in which a pin 25 on the part 21 engages with lost motion. If, from the extended position shown in full lines, the jack piston is moved inwardly, the initial movement of the lug 24B and link 28 causes the notch 27A to be disengaged from a pin 22D on the part 22, thus freeing the stay 21, 22 for folding. At the end of the retractive movement, the other notch 27B engages a pin 29A on a bracket 29 on the fuselage. Similarly, in extending the leg 20, the initial outward movement of the jack piston disengages the notch 27B from the pin 29A. In a simpler construction, Fig. 1 (not shown), the locking-pawl is singleacting and serves only to lock the stay in an extended condition, while in a further construction the jack piston co-operates with a bell-crank lever, and separate locking-pawls are provided for retaining the leg in its two extreme positions. If desired, the jack cylinder and piston may, as shown in Fig. 5, be incorporated in one part 52 of the stay 51, 52, the outer end 53 of the piston moving in a slot 52A and being connected through a rod 55 to a link 56 which controls the locking pawl 57. In another modification, Fig. 6, the leg 61 of a retractable tail-wheel unit is locked in its extended position by a bolt 68 engaging a fuselage recess 69A the swinging movement of the leg and the operation of the bolt 68 being regulated by pistons 66, 68A, moving in cylinders 56, 67 to which fluid pressure is admitted by pipes 71-74 to yield a series operation. Specification 454,279 is referred to.

Title: Improvements relating to the measurement of conductivity of liquids
Inventor: FIELDEN JOHN ERNEST
Filed: 1951-05-03
Abstract: 695,058. Measuring electrical conductivity of liquids. FIELDEN (ELECTRONICS), Ltd. May 2, 1952 [May 3, 1951], No. 10381/51. Class 37. A current is induced electromagnetically in the liquid under test and the magnitude of the current is measured as an indication of the conductivity of the liquid. In Fig. 1 the liquid flows through two glass tube branches 2, 3 forming a closed loop linking transformers 4, 5 so that branch 2 is the secondary of transformer 4 and feeds branch 3 forming the primary of transformer 5 whereby with change in conductivity of the liquid the secondary 7 of transformer J feeds a correspondingly varied voltage through an amplifier 8 to actuate an indicator 9. A balancing winding 10 may be provided and to avoid interaction the transformers 4, 5 may be staggered as shown, or at right-angles with in this case the tube branches skew. In a second arrangement, Fig. 2, the closed tube loop 12 forms a closed circuit secondary of a transformer 13 whose primary 14 constitutes the test variable arm of a normallybalanced A.C. fed impedance bridge. A change in conductivity of the liquid in the loop 12 produces a change in the reflected impedance of the primary 14 and thus a bridge out-of-balance voltage of phase sense corresponding to the sense of the change in conductivity of the liquid. This output voltage is fed to a phasesensitive amplifier 18 and Fig. 3 (not shown), whose output in turn drives a servo-motor 19 in the appropriate direction to adjust bridge zeroizing potentiometer 20 and move an indicator or pen 21 to indicate or record the change in conductivity. Fig. 2 may be modified to provide an arrangement wherein the transformer core and winding 14 covered with an insulating material are immersed in the liquid leaving the space within the core open.
